What it is

Screenbox provides self-hosted virtual desktops for AI agents, with real browsers and desktop applications. Each desktop includes Chromium with DevTools and extensions, plus tools such as file managers, terminals, and office applications. Agents can use 21 MCP tools across more than 100 actions, including screenshots, OCR, clicking, typing, shell access, file operations, and clipboard control. Screenbox connects to MCP clients such as Claude Desktop, Claude Code, and Cursor through stdio, streamable HTTP, or SSE. Its dashboard supports live desktop viewing, agent management, snapshots, knowledge browsing, and session logs. Users can save and restore desktop state, including files and browser sessions, or clone desktops from templates. Session action logs can be compiled into reusable facts for future screenshot and look responses. Users can watch activity through RDP or noVNC and take mouse and keyboard control. Desktops run in Docker containers with memory limits, network isolation, and no bind mounts, but the maker cautions that these are not hardened sandboxes. The software runs on Linux with native Docker, macOS with Docker Desktop, and Windows with WSL2. Each desktop uses about 2 GB RAM and needs no GPU.

For and against

For

  • Provides 21 MCP tools across more than 100 actions
  • Includes Chromium and desktop applications
  • Users can watch agents and take control
  • Supports desktop snapshots and templates
  • Maker says self-hosted software sends no telemetry

Against

  • Docker containers are not hardened sandboxes
  • Each desktop uses about 2 GB RAM
  • Maker advises against exposing the MCP API publicly

The verdict

Screenbox combines agent-operated desktops with session visibility, snapshots, and human control. Its container isolation is not presented as a hardened sandbox, and the maker recommends restricting MCP API access.
